Interesting that you are using 24V and not 48V especially since you are running DC up the tower where voltage drop may be a concern. I realize the WS-12-250-DC's will automatically up-convert to whatever, but they are more efficient if you feed them a higher voltage (~48V). If you already have 4 batteries at the base, what is keeping you from using a 48VDC rectifier?
Would you mind sharing the approximate cost of that ICT? Off-list is fine if you would like. Thanks, Josh On Thu, Apr 28, 2016 at 12:01 PM, Scott Vander Dussen <[email protected]> wrote: > Thanks!
